Resumen : The effects of artificial diets were studied with different store times, between 1 week and 6.5 months in juveniles culture shrimps in fattening phase. The artificial diets were stored at environmental temperature. The quality of raw materials and finished products were controlled during the storage time with physical, chemical, organoleptical and entomological analysis also it was evaluated the growth, protein efficiency, the food conversion factor and the survival of the shrimps. The nutriments affected during storage were the proteins, lipids and the % of free fatty acids, due fundamentally to the contamination with acarids and insects. It was found that the growth and protein efficiency of juveniles shrimps decreased with the age of the feed, without mortality, the best results were obtained with the 2.5 storage months diet. It was detected the presence of Aphlatoxin B1 in three of the storages in quantities within the established limit for animal food, this affected the growth, but not the survival. It was found that the cost of shrimp culture can be increased by concept of feed between 96 to 535 US$/t of shrimps if feed is consumed with more than 2.5 months of storage, this would reduce the economical efficiency of the production action of the enterprise. It is recommended not to extend the storage feed period more than 2.5 months due to the economical looses which represents deterioration that produces low improvement in the animals.
